JAMES A. KEYES, orv NEW YORK, N. AssIeNoRA To. UNITED WRAPPING MACHINE COMPANY, or CHICAGO, ILLINOIS, A CORPORATION or ILLI- NoIs,

Be it known that I, JAMES A. KEYES, a

. citizen of the United States, and aresident of New York city, in the county and'State of New York, have inventedcertain new and useful Improvements in Machines for Wrapping Articles, lofwhic'h the following is a specification, taken in connection with the accompanymg drawings, which form a part kof the same.

l This linvention relates to machines for wrapping article'sand relates especially to y the center ofthe mold wheel.

tail showing the paper feeder. Fig. 4' is a vmachines in which the articles are wrapped in mold wheels being transferred from one mold wheel to another during `the wrapping operation.

In the accompanying drawings in which the same reference numeral refers to similar parts in the several figures Figure 1 is a side view partly in 'section of a machine embodying this invention. Fig. 2 is a similar view, the line of s ection'being substantially through Fig. 3 is a deperspective view of the same. Figs. 5, 6, 7, 8, 9, 10 and 11 show details of the folding and tucking mechanism and its operation in wrapping an article. Fig. 12 shows a detail I of the wrapper strips.

In the embodiment of the invention shown in the drawings, a rigid frame 1 is rovided supporting the main shaft 2 in suita le bear-fI ings and .alsosupporting the cam shaft 37 in similar bearings so as tobe parallel to the main shaft. The sprocketchain 70 driven by the sprocket wheel 69on the main shaft engages a similar .sprocket wheel 83 onthe cam shaft'v so as toj'rotate these two shafts in unison. The foldingwheel 5 1 and the tucker wheel 81 are secured upon the shafts 30, 31 and are rotated intermittently so as to bring the molds in these wheelsinto alinement, the

articles being forced into the molds of the folder wheeltogether with the wrappers fed thereto by the paper feeder. The folding wheel 51 and the tucker wheel 81 will both be lreferred l.to throughout the specification broadly as wrapping wheels for they each perform different steps in the wrapping of the article.

The paper feeder for feeding the wrappers 'to the folding wheel comprises an auxiliary feed for withdrawing the paper from suitable reels mounted at the top of the machine 1n Patenteamay 7, 1907. i.

any desired way. This auxiliary feed may -be in the form of the feed, roll 100 mounted upon the shaft 99 and preferably rotated at a speed slightly in excess of the desired speed `of the wrapper by a suitable belt 101. A

suitable looper is preferably employed to assist in the feedof the paper and the looper indicated in Figs. 1 and 2 may be used. This comprises a looper roll 98 pivoted about the arm 102 which swings about the in 97 in the upper part 16 of the frame. This looper roll when moved into the position indicated in -2 forms a loop between the auxiliary feed roll 100 and the idle roll mounted upon the pin 97 and as indicated in Fig.- I the looper arm 26 connects the lower part 103 of the looper arm with the crank 116 secured to the vshaft 22'. The paper strip passes between the cutter roll 25 and the cooperating feed roll 24 although any otherl desired` mechanism may be employed to feed forward and sever the separate wrappers from the paer strips. The cutter roll is indicated as ormed with the knife having yielding guardson either side of the same pressed out- Ward by the springs 78, this knife coperating with a suitable cutting face 79 mounted in the channel 77 in the roll'24. As indicated,

ythe knife and guards are mounted in the channel 76.

The cutter roll and feed roll are geared together by the cooperating gears 21 and the cutter roll is lalso preferably provided with the alining members 73 each of which as indicated in Fig. 3, is formed with a point 72- which is normally retracted beneath the sur- -fac'e of the roll 25 by the spring 7 4 acting on the head 75. This alining member is, however, provided with the pin 89 which co- `operates with the cam 86 held in stationary -position so that when the pin rides up on the cam the point 72 of thc*aliner is protruded beyond the surface of the roll. The feed roll 24 is formed with a hole S7 to accommodate the point 72 and also is formed with the depression 117 by which the grip between the tworolls is interrupted at the time the alin- .irg memberacts.. The aliningv member coo rates with the presser 18 mounted u )on tlrie presser bar'84 which is held d ownwar by the spring` 19so'that the prossersengage the paper strips as they pass over the cutter roll, ,these pressers beingy formed with suitable slots 88 through which the point-s of the aliners may protrude. yA suitable'pivoted latch 17 is pivoted about the arm 85 on the presser bar and this latchy as is indicated in Fig. 1is adapted to engage the -83 so that the pressers may be held out o contact with the cutter roll.

Two strips of paper may 'be' used to wrap l the articles and either the outer wrapperilO? or the inner wrapper 108 may bey printed with suitable advertising matter or in other ways. Y When these wrappers-are printed the --alining holes 83 are formed in them which always bear'a fixed relation to the printed matter on the wrappers and to the pro er line of severance between them. The b anks 106 .are preferably not entirely punched out of the paper strips but` are joined b tongues 105 as indicated in'Fig. 12. .he paper strips fed by the auxiliary feeder are engaged by the cutter roll and feed roll by which they are severed into separate wrappers and the .wrappers are broughtinto accurate alinement before being fed forward by the alining pins which are protruded by the mechanism described so as to enga e the holes 83 in thev strips and protruding t irough the slots 88 in the pressers slightly adjust the longitudinal position of the wrappers while the grip of the cutter roll and feed roll is released by reason of the ydepression 117 (see Fig. 4). 7 At this time, also, the movement of the looper roll furnishes enough slack so that the paper strips can readily be drawn forward and aliv When this is. ef-

solute alinernent secured. fected the further rotation of the cutter roll and feed roll positively grip the-paper, feed it forward the length of the wrapper and the cutter 80 thereupon severs it.

The double wrapper 20 is by this Ameans supplied at the roper intervals in front of the mold in the folding wheel, as indicated in Fig. 1. ,As indicated in that figure, the feed roll is rotated lby a suitable sprocket chain .104fwhich is purpose.

driven by a sprocket on the cam shaft 37 ,although the paper feeder may be operated in any other desired way in conjunction with the other mechanism.

The tucking wheel 81-is rigidlysecured to the shaft 31 which is mounted in suitable bearings in the frame and this wheel may be provided with any desired number of suitable molds about its periphery. These mold are formed bythe plates 49 removably secured at one side of the molds by the screws or bolts 57. The movable sidee 50 are ref -l erably pivoted about the pins 82 in the W eel. As s eenin Figs. 1, 7 and9 these sides 5() are forme'dwith the arms 55 which' are' spring pressed intoen agement with'the stationary' cam. 94 on the s aft 31 which cam may be se# cured. to a part of the frame' not shown, a suitable spring 56 being indicated for this The folding ywheel 51 is similarly secured to the shaft 30 and is rovided in a similar Way with molds. about yits periphery,

-oted about the point 4, see Fig. 2.

lever is connected at the point 163 by the link? @easel .these molds having the removable plates 49 at one side and the movable sides 50 at the opposite side ofeach `mold controlled by the cam 95. It will be seen that the. removable Vplates in the two wheels are in alinement and thatby employing suitable washers or other means the position of these plates maybe readily altered in the two wheels, lso that Vmolds 'may be formed of different width.

The two -wheels are geared together by the ears 548, 59 secured tothe shafts and the oldingiwheelds intermittently rotated by a' Geneva stop movement operated 'by a suit" able roll 66 on the arm 65 secured to the cam i shaft 37. This roll engages the radial slots 115 in the star wheel 114 indicated in Fig. 2, so as to give an intermittent rotation to the .mold wheels, the circular segment 166 serving to engage the circular recesses .in the star wheel to hold the mold wheels in avlinement at 'formed with convex working faces, as yindicated, so. thattheir working faces substantially correspond to the circumference 'of thev wheels and secure they complete ejection f articles therefrom. The'plungers of the wheels are positively moved at interval the ejector pins 63, 64 .on thek ejectorfit? which is pivoted about the point 41 at .the

bottom of the frame. This ejector is proe vided with a suitable roll 39 engaged by the ejector cam 40. which gives a simultaneous movement tothe two ins 'thus throwing all the horizontally locate plunger rods andl the four plunge'rs attached thereto to one side to transfer and eject the articles. to be wrapped are supplied in any desired way and may be brought forward along the upper run 11 of a suitable belt, the lower run of this belt'being indicatedas 1 5.l The arti- The articles v IIC cles are fed into the folding wheel at intervals by the feed plate 12, which as is indicated-is mounted on a suitable lever 13 piv- This 62 with the ejector so that the ejector and feed plate move' in unison. plate operates, however-,. the support 14 is Before the feed movedtowardthe wheel-,this su port'being mounted-on the lever 3 pivote pin 4 and operated bythe cam 7 1 on thema'in shaft which engagesa` suitablerollv 5 onfthe lever. The guide 10 is pivoted on thel upper end 6 of vthis lever and has alsuitable rojecm tion 9 Whchengages they curveden of an arm 8 mounted on the bar 7 of the frame. Asthis support moves upward thef'guide is allowed to drop downward-as soonfas the n,

.ilesportion 9 moves away from the coperating part 8 and thus the article is guided both above and below at the time the feed plate folding wheel wrapper,

-with it, the ends of the outward on eitherside of the article, the

forces it forward into the mold inthe folding wheel.

' AThe wrapper 2O which may be a double as indicated, is supplied at the roper intervals in front of the mold of the and the article forced into the carries the wrapper mold' by the feed plate wrapper projecting length of these projecting ends being subfend of the wrapper and fol folder operated by the shaft.

.the link 33 connects the upper end of this adjacent the Y erably provided with lever with the arm 29 so that the rotation of thecam shaft in the direction indicatedby the arrow imparts an oscillation to'this folder and moves itinto the position indicated in Fig. 5. The stationary folder is mounted folding wheel and is preferably continued inthe form of a guard around this wheel being supported by suitable pins 61. The forward movement of the folder wheel when it is intermittently rotated brings the lower projecting end of the wrapper 20 into engagement with this stationary folder and forms the longitudinal fold 109 in the wrapper, the oscillating folder 28 being withdrawn about this time. A the guard or continuation of the stationary folder until the partially Wrapped article has made a half revolution and is brought into alinenient with the cooperating Vmold in the tucker wheel 81. This tucker wheel is p'ref- -tucker plates 53 secured at either side of each ofthe molds, as indicated. in Figs. 6,7 and 8. The ejector operated in the manner described throws the plungers 48v to the left and thusI transfers the partially wrapped article from the folding wheel into the cooperating mold of the tucker wheel, thismoveinent causing the projecting ends of the wrapper to, iinpinge upon the tucking plates 53 at the endsl of the inoldsso that thetop end fold 111() is thus formed in the wrapper at either end of the article. It will be noted that the stationary cams 94, 95 on the shafts of the mold wheels are soshaped that the spring pressed sides of the molds are released at the time Vwhen articles are inserted or discharged from the molds, while at other times the articles are gripped with :the desired pressure by these movable sides.

A suitable setter 27 is preferablyfprovided secured to the frame and located in suoli position that the plungers 48 are brought into the proper position as the molds into position to' receive an article.

This folder This fold is held down by* are rotated This setter 27 consists of a fixed bar supported by the frame and extending into the 'path' of the lungers. f

The stationary tuckers 44 are secured to the sides 93 of the discharge chute 92. The oscillating tuckers 45 are secured to the tucker shaft 118, the arm 47 on this shaft being pivoted to the tucker bar 46 which is also 7 5 pivoted to the sleeve of the arm 29 of the oscillating folder 2,8 sol that the oscillating folder andthe oscillating tuckers operate in unison, see dotted lines, Figf2. vWhen' the articles in the tucking wheel 81 are brought 8o toward the discharge chute, the oscillating tuckers 45 are withdrawn into position indicated -in Fig. 7 so as to be out 'ofthe path of the projecting wrapper ends.' The further movement of the tucking wheel will under 85 these conditions bring the projecting ends of the wrappers into engagement with the staftionary tuckers 44 so as to forni one of the side end folds 1 11 at either end of the article. Thereupon when the article. is brought into 9o alinement with the discharge chute,-the oscillating tuckers 45 operate and form the opposite side end fold 112, as indicated in Figs.

8 andll. At this time, the ejector operates and the ejector pin 64 engages the short pin 9 5 on the plunger 48 and moves this plunger outward, the pin 64 being accommodated by the slot 91 in the tucker plate 53see'Fig. 1.

'This forms the top end fold 113 at either end of the article and also forces the article into ico theldischarge chute, pushing the preceding articles ahead of it. 1

l It is, o f course, understood that those fa? miliar with this `art may make manyvariaftions in the. number, proportion and arrange-1i o 5 ment of parts of this machine, parts of the v saine may be used without employing the whole, and parts may be used-in connection with other devices without departing from the spirit of this invention or losing the adi io vantages of the same'.v I do not,- therefore, desire to be limited to fthedetails of. the disclosure which vhas been made injthis ease, but
